Solderbox is a compact semimodular synthesizer, made in collaboration with Jakob Haq. It is heavily based on Jakob's own modular rack design (which features a lot of modules made by hand). The app is designed to offer a set of modular functions that is both comprehensive and eclectic, including several tools for generative synthesis, random signals and the surgical mangling of audio waves and modulation signals. A lot of effort went into making everything sound and behave as analog as digitally possible (with the exception of the unashamedly digital Entropy lo-fi effect processor). Additionally, the built-in Instability Engine injects the subtle fluctuations simulating the effects of crosstalk, leaky signals and expired electrical components. This is a living instrument with a soul of its own. - Full Audio Unit compatibility (AUv3 instrument, audio effect) - Universal design (iPhone, iPad, MacOS AUv3) - Built-in Pulsequencer (LFO-based generative melody generator with custom scales) - 4 mode Low-pass filter (6, 12, 18, 24 dB) - 3 voice polyphony - Drone mode - Stackable patch cables - DIY Lo-Fi digital delay circuit emulation - All synth settings exposed a AU Parameters (for automation and MIDI learning in your host of choice) Find the user manual on ruismaker.com
